How it works and what it consists of lightning
Reliable lightning protection system to protect your home from lightning strikes and possible fire, if you have a wooden structure. In this article I will talk about what parts realized literate lightning and how to perform it.

How the system works
So, first things first, let's see what principle operates lightning private home ownership.
On the picture above you can see all the elements that are included in the lightning protection. And the principle of the whole system is that the metal current collectors placed on the roof, take on lightning discharge, which is further forwards through a special tokovod charge on the ground circuit located near building.
Let's now talk about each item separately lightning.
security features
Lightning
The main function of air terminal - is to take a lightning bolt on, so the selection of this element should be taken very seriously. At the moment, can serve as such a receiver: classical pin, coarse mesh, wire itself or a metal mesh.
Pin
This is the most common and familiar to all kind of air terminal. In the market you can find many ready-made solutions. Basically, this security element is made of copper, steel and aluminum. But it is considered the best copper Lightning. Thus for a successful lightning discharge energy receiver section should be at least 35 square millimeters for copper or at least 70 square millimeters for steel and aluminum. Long as they can be from half a meter to two meters. Mainly installed in the private sector.
Metal grid
This type of air terminal is used on large areas of the buildings, apparently carried out in the form of cellular carcass assembled from a valve thickness of at least 6 millimeters, and the dimensions of the cells may vary from 3 to 12 meters. In this installation of such a network is carried out in the region of at least 15 cm in the roof.
Cable
This type of receiver is directly mounted along the roof ridge. In this case, the cable must not be thinner than five millimeters. Just this kind of receiver is mainly used in the private sector.
The very same roof can be used as an air terminal, where two very important conditions are met. Firstly, the metal from which the roof is made, must be thicker than 0.4 mm, and secondly under it should not be flammable or flammable materials.
The collector
As a collector used bare wire made of copper, steel or aluminum (better course from the copper) with a minimum diameter of 6 millimeters. Thus the handler must pass along the shortest path from the air terminal to the grounding circuit. A compound must be made by welding or bolts.
As the collector is to be hidden, for example, in the cable channel.
ground loop
And last in the list (but not least) elements of a lightning protection grounding contour. How to properly implement, detail It is written in this article. Here I want to say that it is to bury the metal structure of the two-meter pins driven into the ground and located in a part of the site, where people are rare.
conclusion
That's all I wanted to tell you about what elements is lightning and how it works. If the article was useful to you, then put his finger up and thank you for your attention!
